Abstract:

Abstracts: Plant transpiration is one of most important physiological function in plant body, it was a great importance that the reason of high velocity of plant transpiration was elucidated. to be based on the anatomic structure of the stomata of plant tissue, the reason of high velocity of plant transpiration by stomata was elucidated with the principles including in the science of meteorology、plant cultivation、mathematics、calorifics etc, viz. to be huge surface area of transpiration、higher temperature in the micro-environment、distinct difference of atmospheric pressure between the inside and the outside of stomata of plant tissue, and more, the reason of high velocity of plant transpiration was elucidated, viz. enlarging the surface area of transpiration by increasing the exponent of the leaf area and enlarging the surface area of transpiration、supplying sufficiently with water. It was the primary reasons of high velocity of plant transpiration including huge surface area of transpiration、higher temperature in the micro-environment、distinct difference of atmospheric pressure between the inside and outside of stomata of plant tissue、great exponent of the leaf area and sufficient supply with water. Finally, a diagrammatic representation of interrelation of correlative factors of plant transpiration was given.
